The mirror's `tests/` exclusion was depth-agnostic, so it deleted `skill-author/assets/templates/tests/` — a template the skill scaffolds FROM — alongside the depth-2 dev fixtures it was meant to drop. Since ADR-0017 makes the mirror the installed content, the shipped scaffolder was broken: the mirror copy of `new-skill.sh` exited 2 on `sed: can't read .../tests/README.md`, leaving a half-written skill, while the byte-identical `.apm/` copy exited 0. `--check` was green about it. Check mode was restructured rather than patched because `diff -x` matches a basename at any depth and cannot express the depth-2 scoping the fix needs — the two modes could not be made to agree by construction. Check mode now runs the real `sync_dir` into a throwaway root and diffs with no exclusions, leaving the exclusion rule and the hooks destination each in exactly one place. Also fixed here, all previously invisible to `--check`: - Merged hooks were written to `<plugin>/hooks.json`, which Claude Code does not convention-scan, while ADR-0017 itself quoted `hooks/hooks.json` as the contract. Moved, with the legacy path cleaned up as stale. No `hooks` pointer is added to `plugin.json`, so this does not reopen the option ADR-0017 rejected. - Only the first drift per plugin was reported: `diff | sed` returns 1 under `pipefail`, and `set -e` killed the subshell before the remaining checks and before `FAIL=1`. - File-mode and symlink drift were invisible, so `--check` and a real sync disagreed; a find-based type/mode manifest now covers both. The tests pinned almost none of this — the stale-skill wipe, the check-mode stale branch, three `MIRROR_DIRS` entries and the hooks newline normalization could each be deleted with the suite still green. All are now mutation-tested. Refs: #90 ADR: 0017 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X7GvKuJfy2WrdBmUttV4DT
skill-author
Author and refine skills conforming to the agentskills.io specification — create new skills from scratch or apply improvement signals to existing ones.
What it does
Routes to one of two flows based on context: if no skill directory exists at the target path, it scaffolds the directory from annotated templates, fills in SKILL.md and supporting files, and validates the result. If an existing skill directory and improvement signals are both present, it groups those signals by root cause and applies targeted edits, then re-validates. In both flows, bumps the skill's metadata.version when present (minor for create, patch for improve).
Before you start
- Run
/grill-meto resolve design decisions before creating a new skill - Collect domain research, examples, and constraints
- Know the skill name (kebab-case) and destination path
Placement
scripts/new-skill.sh resolves the mode automatically by walking up from the given path — see SKILL.md Step 1 for the full algorithm.
| Mode | Path | Chosen when |
|---|---|---|
| Standalone | <path>/<name>/ |
No apm.yml with a top-level type: field is found walking up from <path>, before hitting .git or the filesystem root |
| Package (APM) | <package-root>/.apm/skills/<name>/ |
A type-bearing apm.yml is found at or above <path> — <path> just needs to be somewhere inside the package |
If the destination resolves inside an APM package, read references/deployment-modes.md — self-containment rules apply to apm compile output the same way they applied to plugin cache isolation.
